[Figure 3] FIG. 3 is an explanatory diagram showing still another example of the embodiment. [Figure 4] FIG. 4 is an explanatory diagram showing still another example of the embodiment. [Figure 5] FIG. 5 is an explanatory diagram showing still another example of the embodiment. DETAILED DESCRIPTION OF THE INVENTION
[0009] Hereinafter, embodiments will be described with reference to the drawings. In Figure 1, 20 is a thin, rectangular plastic bag made, for example, of polymer resin or fiber, and has an opening 30. Plastic bags 20 are available in transparent and translucent varieties. When placing a product in plastic bag 20, opening 30 is opened by pulling side sheets 21 and 22 apart from the opening 30 side.
[0010] In this case, since the plastic bag 20 is made of a sheet having a thickness of about 0.2 mm to 0.8 mm, it is difficult to open the opening 30. However, according to this embodiment, in the area near the opening 30, the first and second parts of the area facing each other near the edge of the opening 30 are provided with processed or treated parts (anti-slip) 41, 42 that are coarser (to prevent slippage) than the other parts.
[0011] For example, a user can place their thumb and index finger in contact with non-slip pads 41 (thumb side) and 42 (index finger side), pinching them together, and then move their fingers in the direction of the arrow to easily create a gap that slightly opens opening 30. Then, the user can insert their fingers into this gap and easily open opening 30 wide.
[0012] This significantly improves the ease of placing products in the bag compared to conventional methods, reducing user frustration. While non-slip surfaces 41 and 42 are provided, the objective of this embodiment can be achieved with just one. These surfaces may also be a different color from the rest of the bag to make them more noticeable. The non-slip surfaces 41 and 42 can be easily added during the manufacturing process of the plastic bag by applying particles with a stamp or by forming uneven surfaces with a press.
[0013] The plastic bag 20 has a variety of uses, such as for carrying umbrellas, for carrying fish, meat, vegetables, etc., and for carrying medicine.
[0014] As described above, this embodiment can be said to have a processed or treated portion in at least one of the opposing regions near the edge of the opening that has a stronger locking effect than the other portion. Also, the processed portion can be said to have an anti-slip function.
[0015] Figure 2 shows another embodiment. Figure 2 shows a partially cut plastic bag 20 with the area on the opening 30 side open. Some plastic bags have zippers to prevent moisture, for example. The zippers are formed by forming a concave rail 51 and a convex rail 52 facing each other on the inside of one and the other side sheets 21, 22 in the area on the opening 30 side. The concave rail 51 and the convex rail 52 are formed thicker than the wall thickness of the plastic bag and are made of an elastic polymer resin.
[0016] When the opening 30 is closed, the side sheets 21 and 22 are pressed from the outside with fingers, so that the convex rail 51 and the concave rail 52 engage with each other.
[0017] In this embodiment, a spacer 60 is formed outside the rail, for example, in the middle of the longitudinal direction of the opening 30. The spacer 60 is made of the same material as the rail and is formed simultaneously when the rail is formed on the sheets 21 and 22. The presence of this spacer 60 prevents the sheets forming the opening from being in close contact with each other, forming a small gap. A user can easily open the opening by utilizing this gap. Even in this embodiment, by performing the operation described in FIG. 1 , the first and second sheets facing each other in the opening area can be shifted to widen the opening (gap) between the sheets, allowing the user to insert their fingers into this gap and open the opening wider. Furthermore, multiple spacers 60 may be formed, rather than just one. Furthermore, it is desirable to position the multiple spacers so that they do not collide with each other, for example, by shifting them vertically on the bag, for ease of operation as described in FIG. 1 . Alternatively, the spacers may be formed as protrusions on the first and second sheets, offset by a small distance from each other on the outer surfaces of the bag, so that the user can grasp and slide them to create a gap between the sheets. The spacer 60 can be formed by applying resin or by pressing. The shape of the protrusions can also be modified in various ways, and may include the date of manufacture or characters such as a commercial.
[0018] As described above, this embodiment can be said to have a processed or treated portion in at least one of the opposing regions near the edge of the opening that has a stronger locking effect than the other portion. The processed or treated portion can also be said to function as a spacer.
[0019] Figure 3 shows another embodiment. Figure 3 shows a plastic bag 100 that customers can obtain at the cashier when shopping at a supermarket or convenience store. The main body 110 of this type of plastic bag 100 has an opening 111. Handles 211 and 212 are integrally formed on both sides of the opening 111.
[0020] Furthermore, tongues 213A and 213B projecting from main body 110 face each other between handles 211 and 212. Anti-slip surfaces 41 and 42 are printed, glued, attached or processed on the outer surfaces of tongues 213A and 213B.
[0021] As explained in Figure 1, when the above-mentioned non-slip pads 41, 42 are pinched between the thumb and finger and slid, the tongues 213A, 213B are misaligned, and the tongues 213A, 213B can be pulled apart, making it easier to open the opening of the shopping bag 100.
[0022] Figure 4 shows yet another embodiment, which shows a bag 400 containing, for example, sweets or biscuits, and has an opening 411 closed by a zipper 410. The zipper 410 has the same structure as that described in Figure 2.
[0023] Furthermore, an opening region 411 extends from the position of the fastener 410, and an opening edge 412A is crimped closed.
[0024] Here, when the user wants to open the opening, he or she cuts off the opening edge 411A side from the cut portion 430 along the dotted line to divide the opening region 411. However, the opening region 411 does not open until the inside of the bag 400 is visible, and is closed by the fastener 410.
[0025] To release the fastener 410, the opening must be opened at the divided portion (dotted line). Conventionally, however, opening the opening was difficult because the opening was closed by the opposing sheet. However, in this embodiment, spacers 60A and 60B are provided on the inside of the sheet, so the opening is slightly open, forming a gap. Spacers 60A and 60B are made of the same material as the rails and are formed simultaneously when the rails are formed on sheets 21 and 22. Due to the presence of spacers 60A and 60B, the sheets on both sides of the opening are not in close contact with each other, forming a small gap. The user can use this gap to easily open the opening. One or more spacers may be used. The method of forming the spacers is the same as that described in the above embodiment.
[0026] 5 is an explanatory view showing yet another embodiment. Spacers 61A and 61B are formed inside the openings 80 of the sheets 21 and 22, respectively.
[0027] At the back of the opening 80, a concave rail 52 and a convex rail 51 are formed on the inside of the sheets 21, 22 along the longitudinal direction of the opening 80, facing each other.
[0028] Here, the protruding direction of the convex rail 51 is inclined toward the opening 80 with respect to the inner surface of the sheet 22 (the direction of the semicircular curved arrow Y1). For this reason, when the concave rail 52 and the convex rail 51 engage, the tip of the convex rail 51 is pressed toward the back of the bag (downward in the drawing) (the direction of the semicircular curved arrow Y2). As a result, a force is applied to the sheet 22 from the convex portion 51 toward the opening 80, in a direction that closes the opening. The opening tends to close in a tight seal.
[0029] However, spacers 61, 61B located away from this rail portion collide with each other, preventing the opening 80 from being in a tight contact state. This makes it easier for the user to open the opening 80 of the bag.
